GENERAL HISTOLOGY

Detailed explanation-1: -Cell walls in prokaryotes serve as a form of protection and prevent lysis (bursting of the cell and expulsion of cellular contents). Structurally, prokaryotic cell walls consist of two layers: An inner layer that is made up of peptidoglycans. An outer layer that is composed of lipoproteins and lipopolysaccharides.

Detailed explanation-2: -The cell is surrounded by a plasma membrane (or cell membrane) to separate the cell contents from the external environment. Biology definition: A cell wall is a structural layer next to the cell membrane with the primary role of giving the cell rigidity and protection from mechanical stress.

Detailed explanation-3: -The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.

Detailed explanation-4: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.
